In this study, the removal of cadmium and lead ions from aqueous solution by nanocrystalline magnetite was investigated. The nanocrystalline magnetite was synthesized by mechanochemical activation of hematite in a high energy planetary mill in argon atmosphere for 45 hours. The ability of the synthesized nanocrystalline magnetite for removal of Cd(II) and Pb(II) from aqueous solutions was studi...

Self-standing, transparent, thick (approximately 90 microm) mesoporous titania-phosphorus oxide composite films containing anatase nanocrystallites were synthesized using the evaporation-induced co-assembly of an amphiphilic triblock copolymer template, titanium tetraethoxide, and phosphorus chloride.

In order to effectively photodegradate organic pollutants, ZnO composite and Co-B codoped TiO₂ films were successfully deposited on glass substrates via a modified sol-gel method and a controllable dip-coating technique. Combining with UV-Vis diffuse reflectance spectroscopy (DRS) and photoluminescence spectra (PL) analyses, the multi-modification could not only extend the optical response of T...

Nanocrystalline niobium carbide (NbC) ceramics and carbide-niobium nitride (NbC/NbN) composites were synthesized at low temperatures without high-pressure sintering using a single-step polymer-derived approach from meltable pre-ceramic blend. Niobium hydride (NbH5) 1,2,4,5-tetrakis(phenylethynyl)benzene (TPEB) reacted 1500 °C under argon or nitrogen in tube furnace to form NbC NbC/NbN with high...
